Abstract

Cette invention concerne un système de transport de particules solides ayant un diamètre compris entre 1/10 micron et 22 mm et formé d'une trémie d'alimentation tronconique, d'un tube cylindrique, d'un cône inversé, l'évacuation des particules solides étant assurée par un tuyau de manutention dont l'axe coïncide avec celui de la trémie, de tubes d'injection d'air dans le bas de la trémie d'alimentation, notamment un tuyau d'injection pénétrant par le sommet du cône inversé et ayant son axe dans l'alignement de l'axe du tuyau de manutention ci-dessus, l'écart entre le bas de celui-ci et le haut du tuyau d'injection étant réglable, et au moins un tube d'injection par le côté du cône inversé. Le système comprend également des moyens commandés par ordinateur de régulation de la température, de l'humidité et du débit de l'air injecté. Puis, les particules solides ainsi fluidisées dans la trémie d'alimentation sont acheminés vers l'endroit voulu. Une variante privilégiée de l'invention sert à projeter dans l'atmosphère un nuage de particules solides servant à bloquer les rayons infrarouges et, ainsi, à soustraire un véhicule équipédu système à la détection infrarouge.
